â¢Major IEC 60601-1 3rd Ed. FDA has announced an official date of 2010-06 when they will accept submissions to 3 rd edition. The EU date of 2012-06-01 has been published in the Official Journal. CB Scheme mandatory use for 3 rd edition varies per the policy of each member country.
Plants and photosynthetic algae and bacteria use energy from sunlight to combine carbon dioxide (C02) from the atmosphere with water (H2O) to form carbohydrates. These carbohydrates store energy. Oxygen (O2) is a byproduct that is released into the atmosphere. This process is known as photosynthesis.
Photosynthesis converts light energy into the chemical energy of sugars and other organic compounds. This process consists of a series of chemical reactions that require carbon dioxide (CO 2) and water (H 2 O) and store chemical energy in the form of sugar.Light energy from light drives the reactions.Oxygen (O 2) is a byproduct of photosynthesis and is released into the atmosphere.hotosynthesis transfers electrons from water to energy-poor CO 2 molecules, forming energy-rich sugar molecules. This electron transfer is an example of an oxidation-reduction process: the water is oxidized (loses electrons) and the CO 2 is reduced (gains electrons).
